Product details

3-Position SMT Header for Tight Wire-to-Board Runs

With a mated stack height of 7.3 mm, this header suits low-profile wire-to-board applications in consumer electronics, medical devices, and industrial sensors where space is constrained.

Pitch, Positions, and Current — Sizing the Connection

At 1.25 mm pitch, the BM03B-GHS-TBT(LF)(SN)(N) fits a compact PCB footprint while maintaining adequate creepage for 50 V operation. The 3-position count is the smallest multi-position option in the GH series, sitting between the 2-position BM02B-GHS-TBT and the 5-position BM05B-GHS-TBT.

SMT Termination and Assembly Features

Surface-mount termination with solder retention and pick-and-place features allow automated assembly.
